Plan of Jekyll Blog - Episode 2: Ruby-3, Jekyll-4, Git, Ubuntu and Nginx

This tutorial you will learn how to configure Jekyll-4 on Ubuntu 16.04/18.04.


Here is the blog repository: blog.old/blog.old3

Jekyll-4 Installation Ubuntu 16.04

First, we should install Ruby3.0.0 for Ubuntu 16.04/18.04:

sudo apt-get install ruby-full build-essential zlib1g-dev nginx
sudo apt-get install gcc g++ make
curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update && sudo apt-get install yarn
sudo apt install curl
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sudo apt-get update
sudo apt-get install git-core zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev nodejs yarn

Then, we can use one of these methods to install Ruby-3:

  1. Install rbenv
cd ~
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 3.0.0
rbenv global 3.0.0
ruby -v
  1. Install RVM
sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm install 3.0.0
rvm use 3.0.0 --default
ruby -v
  1. Ruby Source Codes Installation
wget http://ftp.ruby-lang.org/pub/ruby/3.0/ruby-3.0.0.tar.gz
tar -xzvf ruby-3.0.0.tar.gz
cd ruby-3.0.0/
sudo make install
ruby -v

Caution: In some area, it’s difficult to visit RubyGems, so you might be change a Ruby Source.

gem source -r https://rubygems.org/
gem source --add https://gems.ruby-china.com/
gem source -u

Finally, install Bundler

gem install bundler jekyll github-pages jekyll-paginate webrick

After installation, you can clone your repository from GitHub or GitLab.

git clone https://github.com/IcingTomato/blog.old.git

Nginx Setup

Well, you can also use Apache which use sudo apt-get install apache2 on Debian/Ubuntu or sudo yum install httpd on CentOS/RHEL/Fedora.

First, install Nginx:

sudo apt-get isntall nginx

Then, configure nginx profile:

root@blog:~# sudo nano /etc/nginx/sites-enabled/default

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        # SSL configuration
        listen 443 ssl default_server;
        listen [::]:443 ssl default_server;

        # Disable SSL, because when it enabled, it blocked 80.
        #ssl on;
        ssl_certificate path/to/your_key.pem;
        ssl_certificate_key path/to/your_key.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html;

        server_name your.domain;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;

        # Rewrited the 404 page to 200
        error_page 404 =200 /404.html;

        location /404.html {
                root /var/www/html/;

        # Rewrited the 403 page to 200
        error_page 403 =200 /403.html;

        location /403.html {
                root /var/www/html/;

Ctrl+O and Ctrl+X to save and exit.

Finally, restart nginx.service

sudo systemctl restart nginx

# On AWS, you must use systemctl to start, stop, enable, disable, restart a service.

GitHub Local Repository Setup

git init
git add README.md
git commit -m "first commit"
git branch -M master
git remote add origin repo_address
git push -u origin master

Git roll back to some commit

git reset --hard 某个commit id
git push -f -u origin master

Jekyll Maintaining Tutorial

You can make a quick start for surfing the Jekyll blog:

git clone -b blank https://github.com/IcingTomato/blog.old.git
cd blog.old
jekyll serve # jekyll s
# => Now browse to http://localhost:4000


Setup _config.yml

# Site settings
title: Your Blog                        # Your blog title
SEOTitle: Jekyll | Ruby                 # SEO title
description: "Hello from Seattle"	    # Your blog description

# SNS settings      
github_username: John Doe               # GitHub account
RSS: true                               # RSS On
weibo_username:                         # Weibo  
zhihu_username:                         # Zhihu
facebook_username:                      # Facebook
bilibili_username:                      # Bilibili  
twitter_username:                       # Twitter

# Build settings
paginate: 100                          # Contents in a page

You can visit Jekyll-Docs/Jekyll中文网-文档 for more support.

On PCs, tablet devices or ultra-wide scale screen there is a sidebar to display your personal profile.

# Sidebar settings
sidebar: true                                           # Add Sidebar
sidebar-about-description: "describe yourself"          # Description
sidebar-avatar: /img/avatar.jpg                         # Your Avatar

Sidebar is a Responsive Layout*, when the display size is below 992px, the sidebar will move to the page bottom. You can visit Bootstrap3 for global CSS settings/Bootstrap 设置全局 CSS 样式

Mini About Me

This module is under your avatar. It will display all your social media account. It is also a Responsive Layout. When the screen size become small, it will move to the bottom of the page. But there is a litte change when it move to the bottom.



# Featured Tags
featured-tags: true  
featured-condition-size: 15     
# A tag will be featured if the size of it is more than this condition value

featured-condition-size means if the tags’ count over 15(or the number you set), it will display on home page.



# Friends
friends: [
        title: "John Doe",
        href: "http://john.doe/"
        title: "村財 師内",
        href: "https://sonzai.shinai/"
        title: "鵜祖田 陽",
        href: "https://usoda.you/"


This Jekyll Blog supports both Disqus and Gitalk, it also supports Markdown Grammar.


# Disqus(https://disqus.com/)


First, we should create a new repository for saving our comments:



And then open Issues option:


Besides, register a new OAuth application:



Google Analytics

# Google Analytics
ga_track_id: 'UA-'
ga_domain:         # Default as 'auto', you can use your domain


Write your first blog

We must put the article, which named as YYYY-MM-DD-your_first_article.markdown, in _post folder. And you can change parameter in the front of the article:

layout:     post
title:      Your First Blog 
subtitle:   Jekyll is Хорошо
date:       1900-01-01
author:     John Doe
header-img: img/title.jpg
catalog: true
    - Jekyll

Jekyll Code Block for Liquid-Like

In Jekyll, some Ruby code block can’t generate perfectly.

So, we can use raw tag to avoid execute liquid or liquid-like code block:

{% raw %}

You can use {% highlight ruby %}{% endhighlight %} for code highlight.


cd your.folder
git clone repo.address
git pull origin master
jekyll build -d /var/www/html/

My Second Jekyll Blog

Here is the blog repository: blog.old2

You can use these command line for configuring the blog:

cd <the folder>
git clone https://github.com/IcingTomato/blog.old2.git
bundle add webrick rake
bundle install --path vendor/cache
git pull origin master
bundle exec jekyll build -d /var/www/html/

First, you need to install some Dependence like webrick rake jekyll.

And then, in my case, I had a PATH problem.

Bundler::GemNotFound: Could not find rake-10.3.2 in any of the sources
~/.rvm/gems/ruby-2.0.0-p451/gems/bundler-1.6.2/lib/bundler/spec_set.rb:92:in `block in materialize'
~/.rvm/gems/ruby-2.0.0-p451/gems/bundler-1.6.2/lib/bundler/spec_set.rb:85:in `map!'
~/.rvm/gems/ruby-2.0.0-p451/gems/bundler-1.6.2/lib/bundler/spec_set.rb:85:in `materialize'
~/.rvm/gems/ruby-2.0.0-p451/gems/bundler-1.6.2/lib/bundler/definition.rb:133:in `specs'
~/.rvm/gems/ruby-2.0.0-p451/gems/bundler-1.6.2/lib/bundler/definition.rb:178:in `specs_for'
Show 28 more lines

I used gem install rake but it was no use fixing the matter.

SO, bundle install --path vendor/cache can help you fix the problem.

This command line generally fixes it as that is the more common problem. Basically, my bundler path configuration is messed up. See their documentation (first paragraph) for where to find those configurations and change them manually if needed.

Git Dual Repository Setup

Everytime I finish my blog, I have to push to two different platform: GitHub and Gitee.

Gitee is a collaboration platform for software development & code hosting in China Mainland.

Because I use Ali ECS Area Hangzhou, it’s hard to visit GitHub, so I have to use Gitee.


cd 'your-repository-path'
git remote add gitee 'your-gitee-repository-address'
git push gitee master    # Push to 'gitee'
git push origin master   # Push to 'github' 

You can also change your-repository/.git/config

	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
[remote "origin"]
	url = 'your-github-repository-address'
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master
[remote "gitee"]
	url = 'your-gitee-repository-address'
	fetch = +refs/heads/*:refs/remotes/gitee/*
